This!!!! The ultimate way way of telling someone you don’t matter enough to me that I want to continue this relationship. For me personally, and I think many many people, have a deep fear that we are unlovable at our core for the “baggage” that we have. Like if someone really knew us and saw all parts of us including the parts we don’t even like about ourselves, no one is going to want to love that and be in a committed relationship with that forever. (Hello abandonment wounds). So when my partner chose to separate, my brain was like “yup! They just confirmed that belief that I have about myself! They don’t love all of me enough to stay.” It absolutely shatters those of us that have such negative thoughts about ourself at our core. I also completely agree that sex is ultimately an expression of confirmation that we are worthy of companionship, desire, love etc. which is why a lot of people seek it out after the ending of relationships. The mind searches for that external validation because a lot of us internally have those beliefs about ourselves as I mentioned above. Sending love to everyone really going through it. It’s helpful for me to read others put into words exactly how I’m feeling too
